Questions

How do I convert STL to PLY?

Drop your STL file on this page, or choose it. Anyfile converts it on your device in a moment and the PLY downloads straight away. To change it first, open it in the 3D viewer.

Is my STL file uploaded anywhere?

No. The file is read and converted by your own browser, and nothing is sent to a server. You can check: open your browser’s developer tools, go to Network, and convert a file. No upload appears.

Can I convert several STL files at once?

Yes. Drop them together and you get one ZIP with every PLY inside.
